NVIDIA Demos content folder only contains Brownstone Demo

My Demos folder only contains the BrownstoneDemo content. Should there be other tutorial related demo scenes here to aid in learning? I was hoping to follow along in the Five Things To Know About Materials tutorial that says you should download the demo scene. This tutorial was at Omniverse MDL Materials — Omniverse Machinima documentation. No other demo scenes seem accessible to me and I have Create 2022.1.2. , am logged in and created a local Nucleus Server.
Best regards,
